To aZZrwtom t may concern.'

Be it known that I, HARRY Josnrrr HIC/K, a citizen of the United States, and resident of Alliance, in the county of Stark and State of Ohio, have invented certain new andvuseful Improvementsl in Shim Plates fory Demountable Rims, of which the following is a specification. 1

The invention relates to a shim plate for the wedge of a demountable rim` for automobile wheels', and the object-` of the. improvement is to provide a simple, standard shim plate for ready and eflicient use in all the varying conditions of service.

" A'The demountable rim' of an automobile wheel is usually clamped in position thereon the draw-bolt; and as this wedge bears'upon the outer free edge ofthe wheel rim, there is a tendency to flatten the curve of this edgeof the rim, thus rendering the wedge ineffective because of the deflection 0f its bearino'.

gain, in the use of these devices, it has been found that the wedge becomes ineffective by reason of a stretching or deflection of the demountable rim where it is acted upon by the wedge; and also that the vwedge becomes ineffective because of a wear of the wedge and adjacent parts, which may be Y caused by a looseness of the bolt permitting Y friction between the parts.

These difficulties are overcome by the use of a shim plate for the wedge so as to compensate for any deflection or wear there may be in the parts, and the present invention contemplates the use of a shim plate havin L-tongues engaging the edge of the whee .rim and abutting the sides of the wedge stem.

The invention may be embodied in the forms' illustrated in the accompanying drawings forming part hereof in which- Figure l is a fragmentary side elevation of the rim and tire of a wheel, showing the 'improved shim plates in position;

Fig. 2, al cross Section on line 2 2, Fig. l, showing the use of a single shim plate;

Fig. 3, a cross section on line 3 3, Fig. l, showing the use of two shim plates;

Fig.y 4, a detached perspective view of a 'simple form of shim plate;

Figs. 5 and 6 Vare detached perspectiveV Fig..7, a detached perspective view of the` preferred `form ofshim; plate for use with spaced wedges and Fig. 8, a fragmentary perspective view showingthe use of the proposed form with a spacedwedge.

Similar numerals `refer to similar partsthroughout the drawings.,

The metalrim 1k for theV rubber tire 2is mounted around the metal'rim 3 ofthewheel by bearing at one side against the liangel: off the wheel rim'and 'on the other side against wedges 5 which are inserted between the metal rims of the tire; a-nd wheel atk intervals aro-und the periphery thereof.

The wedge is usually if not universally,

providedwith an L-stem 6which is provided withl an elongated eye 7 for `receiving the draw-bolt 8 extending*throughrthe felly 9of the wheel, which boltis employed for secaring and clamping the wedge for holding the i tire rim firmly against its bearing on the side of the tire rim from the adjacenty side of the Wheel rim.

- flange 4 of the wheel rim, and at the same 'f time wedging and properly spacing the vfree The shim plate 10 is provided with iianges Y on one side edge at each end, which may be in the form of the simple L-tonguesll as yshown in Fig. 4'. These flanges or tongues are arranged to engage the side edge of the wheel rim 4,' while the intermediate vedge portion 12 ofthey shim plate may abut the vinner angle 13 of the wedge stem; and the the shim plate, it is evident that the same is securely and positively held in position Vwhen placedv under the body of the wedge 5and that it can have nowindependent movement upon the wheel rim; other than such movement as the wedge may have thereon, such movement of the wedge' on the Wheelrim being usually prevented by the clamping action of the bolt 8. l

And vit is also evident that the lstem 6 of the wedge may be drawn into contact with` the rim of the wheel, so thatthe full effect of the thickness of the shim plate 10 is obtained when it is placed under the body portion of the wedge; which is not the case if the shim plate itself provided with a seeuring stem located betvveen the rim of the Wheel and the stem of the Wedge.

It is also obvious that the Wedge plate may be folded upward to extend over the Wedge, as shown at 10a in Fig. 5,`or directly upon itself to extend under the Wedge, as shown at 10b in Fig. 6, for thepurpose of reinforcing the thickness of the Wedgeby a plurality of thicknesses or' the shim plate; and also that the flanges or tongues may be folded upon themselves to increase their thickness, as

shoWnat lla and 1lb in'Figs. 5 and 6; all Without departing from the spirit of the invention. Y

In event the stein of ythe Wedge is not 'drawn into contact with the edge of the YWheel rim, either because the lower endet the stem 6 is provided with a riblfh'l as' shown for the spaced form of Wedge in Fig.-

8 or otherwise, it is preferred to use the 'forni of Wedge plate 10C shown inl? ig. 7, wherein the bend 15 of theflange or tongue 11C is corrugated upward at its innerportion to form an extended abutment 16V for impinging the side of the body portion of the Wedge 5. Y v

It Will be understood that a plurality oil wedge plates l0, as shown in Fig. 3, and in such case the edge 12 of the outer shim platermay abut the angle of the stem of the Wedge, and the tongues l1 of the same shim plate lap over the tongues of the innerl shim plate, thus holding all the plates against movement in any direction when the Wedge is clamped into position. more, the improved form of shim can be inserted and removed from under the Wedge Without necessarily Vremoving lthey bolt by which the Wedge is held or clamped in posiing the edge of the rim of the' Wheel and` abutting the side yof the wedge. Y

2. A shim plate for a demountable wedge on the rim ofa Wheel, said shim plate having Furtherv 40` tion; it being only necessary to loosen the n an Lv-tongue onv each side oit the Wedge for Y engaging the edge of the rim yof the Wheel and abutting the side of the Wedge;

3. A demountable wedge for the rim of a Wheel having an L-stein at.y the edge of the rim and a shim plate bent to reinforce the thickness of` the Wedge by ak plurality of Y thicknesses of the shim and having a flange v on each side of the Wedge engaging the edgel oi' the rim and abutting the side of the Wedge.'
